there are lots of potential nasty situations that can happen but I

generally, if the app you updated modifies its data format and
cannot revert it then the user is SOL - but that's not _THAT_
common and when it does happen it's certainly not yum's fault.
If it isn't that common, could yum have added directives to its
configuration ( similar to " exclude= " ) ?
This could increase the reliability of " yum downgrade " in the eyes
of those that use it.
MySQL and PostgreSQL come to mind.
/etc/yum.conf might have " nodowngrade=mysql-server postgresql-server
" in the default file.
That's easier than carrying that info in the package or repo files.
When additional packages are found to be not downgradable, they can
be added to the list.
Granted, if there are a lot of packages, that gets unwieldy.
Also, it could break a downgrade transaction.
